Thermal sweating head manikin ALEX
Device description and purpose
The thermal sweating head manikin 'ALEX' is a high-resolution, multi-segmented device designed to operate in a wind tunnel, with adjustable inclination relative to airflow and the ability to simulate solar radiation.
The head manikin can be used to:
- Determine the thermal and evaporative properties of headwear and protective headgear in accordance with relevant standards;
- Compare samples with earlier prototypes, competing products on the market, or required performance criteria specified in standards;
- Simulate customized real-life scenarios to evaluate headwear performance under actual conditions of use.
